MACHINE FOR GLUING ON BOTTOMS OF WOODEN BOXES.

SPECIFICATION forming part of Letters Patent No. 618,375, dated January 24, 1899.

Application filed November 10, 1897. Serial No. 658,035. (No model.)

To all whom it may concern.-

Be it known that I, CHARLES H. BUMP, a citizen of the United States, residing at Brandon, in the county of Rutland and State of Vermont, have invented a new and useful Machine for Gluing on the Bottoms of Wooden Boxes, of which'the following is a specification.

This invention is designed to facilitate the construction of wooden boxes which have the bottoms glued to the sides and ends and aims to provide a machine for causing the registry of the bottoms and box-bodies and retaining the bottoms in place until the glue sets or hardens.

An essential feature of the invention is the provision of a fixed body for supporting the boxes and a box-passage having adjacent sides adjustable and yielding and one side fixed, said fixed side being contiguous to the bed, thereby adapting the machine for different-sized boxes and for variation in boxes of a given size. This passage is of such a length as to insure a setting or hardening of the glue before the box emerges therefrom. Aplunger cooperates with the passage to force the boxes therethrough and is driven by mechanism forming no part of the present invention, but which will be described at length as the nature of the invention is unfolded.

For a full understanding of the merits and advantages of the invention reference is to be had to the accompanying drawings and the following description.

The improvement is susceptible of variou changes in the form, proportion, and the minor details of construction without departing from the principle or sacrificing any of the advantages thereof, and to a full disclosure of the invention an adaptation thereof is shown in the accompanying drawings, in which Figure l is a perspective View of a machine particularly designed for attaining the ends of this invention. Fig. 2 is a side elevation. Fig. 3 is a transverse section of the box-passage on a larger scale. 'Fig. 4 is a detail View showing the means for throwing the plunger-.

actuating mechanism into and out of gear.

Corresponding and like parts are referred to in the following description and indicated in the several views of the accompanying drawings by the same reference characters.

The machine comprises a suitable base 1,

plate 5 islocated at the inner end of the bed and joins the plate 4. The plate 4 and bed 3 constitute fixed sides of the box-passage and are metal-lined to resist wear and enable the boxes to pass more readily through the passage. A

bar 6 is located opposite the plate 4 and constitutes a side of the passage,and its inner end is curved slightly to facilitate the entrance of the boxes into the passage. Brackets 7, having adjustable connection with the bed, support the bar 6 and enable the latter tobe moved toward and from the plate 4 to increase or decrease the passage, according to the size of the boxes moving therethrough; The horizontal portions of the brackets 7 are slotted, as shown at 8, and binding-screws 9 pass through the slots and enter the bed 3 and serve to hold the brackets and the bar 6 in an adjusted position. Threaded stems 10 project from the bar 6 and pass through one of a series of openings 11 in the vertical members of the brackets 7 and receive thumb-nuts 12 011 their projecting ends, thereby providing for adjusting the bar 6 toward and from the plate 4. Springs 13 are mounted on the threaded stems 10 and are confined between the bar 6 and the vertical members of the brackets 7 and admit of the bar 6 yielding, so as to exert a lateral pressure against the boxes passing through the passage. The bar 6 can be moved up or down by passing the nected by means of bolts 17 and thumb-nuts 18. The upper set of brackets are constructed in every particular in substantially the same manner as the brackets 7, and the same parts are indicated by like reference-numerals. A bar 19, forming the top side of the box-passage, has yielding and adjustable connection with the upper brackets in substantially the same manner as the bar 6 with the vertical or bent ends of the brackets 7, thereby providing for the yielding of the bar 19, so as to exert a pressure upon the boxes in a direction at right angles to the bar 6. The inner or front end of the bar 19 is curved slightly away from the plane of the bed to give a slight flare -to the entrance of the box-passage to facilitate the passage of the boxes therein.

A transverse shaft 20 is journaled in the pillow-blocks 2 and is provided at one end with a friction-pulley 21 and has a wrist-pin which is connected by means of a pitman 22 with the stem 23 of a plunger 24, by means of which the boxes are forced through the passage when the machine is in operation. A second shaft 25, parallel with the shaft 20, is journaled in bearings in the pillow-blocks and is provided with a friction-pulley 26 to make contact with the friction-pulley 21 when it is required to operate the plunger. A bandpulley 27 is secured to the shaft 25 and has motion imparted thereto from a convenient source of power by means of a belt 28. A block 29, forming a bearing for one end of the shaft 25, has the edge remote from the friction-pulley 21 inclined, whereby upon moving said block downward the frictionpulley 26 is brought forcibly into contact with the friction-pulley 21 for imparting movement thereto and to the plunger. This block 29 is movable in a recess 30 of corresponding shape formed in the pillow-block adjacent to the friction-pulleys and is normally held elevated by means of a spring 31, interposed between it and the bottom side of the recess 30, said spring having its end portions seated in openings in the opposing faces of the parts 29 and 30. A lever 32 is pivoted intermediate of its ends to the block 29 and at its outer end to the recessed pillow-block, and its inner end is connected with a treadle 33, pivoted to the same pillowblock as the lever 32. By pressing upon the treadle 33 the block 29 is lowered and the friction-pulleys 21 and 26 brought into contact and the plunger set in motion, so as to force the boxes through the passage.

The inclined wall of the recess 30 forms a way upon which the movable bearing 29 slides and has a tangential arrangement with reference to the driven pulley 21 to cause the driving or friction pulley 26 at the outer end of the shaft 25 to engage by a wedging action with the periphery of the driven pulley 21 upon moving the free end of the shaft 25 downward. The movable bearing 29 is slidable tangentially with reference to the driven pulley. The end of the driving-shaft 25 has ample play in the fixed bearing to permit of the driving-pulley 26 moving tangentially, or, if desired, said end may be mounted in a pivoted bearing, as commonly practiced in the art when mounting shafts, so as to admit of one end having alimited play. In order to insure the driving-pulley engaging by a wedging action with the driven pulley, the way upon which the bearing 29 is slidably mounted is arranged so that the drivingpnlleycannot pass by the driven pulley when lowered, but is caused to crowd thereagainst by a wedging action.

The inner ends of the bars 6 and 19 terminate a distance from the end plate 5, thereby forming a space at the receiving end of the box-passage to enable the operator to place boxes in position to be engaged by the plunger and forced through the passage. These boxes, which are assembled in the usual way, have glue applied to the lower edges of the sides and ends and the bottoms placed in position, after which they are placed upon the bed 3 in advance of the plunger and between it and the passage through which the boxes are forced when the plunger advances. When one or more boxes are in position, the operator presses upon the treadle 33, which throws the plunger in gear, when it is advanced and pushes the boxes through the passage, which latter, as hereinbefore stated, is of a length to insure the setting of the glue prior to the emergence of the boxes therefrom.

Having thus described the invention, what is claimed as new is 1. In a machine for gluing the bottoms to boxes, the combination of a fixed bed for supporting the boxes, a fixed plate at one side of the bed forming a rigid guide, longitudinal bars arranged about centrally opposite to the bed and plate, respectively, means for yieldingly supporting the bars to permit of them having an outward movement and limiting their inward movement, and means for moving the boxes through the passage formed by the bed, guide-plate, and bars, substantially as set forth.

2. In a machine for gluing the bottoms to boxes, the combination of a fixed bed for supporting the boxes, a fixed plate at one side of the bed forming a rigid guide, supports, adjustable mountings for the supports, whereby theyare capable of movement toward and from the bed and guide-plate, longitudinal bars placed opposite to the said bed and guide-plate and forming a passage therewith, yielding connections between the longitudinal bars and the aforesaid supports to limit the inward movement of the bars and permit them to move outward, and means for moving the boxes through the said passage, substantially as specified.

' 3. In a machine for gluing the bottoms to boxes, the combination of a bed, a plate at one side of the bed forming a rigid guide, bars disposed opposite said bed and guide and forming therewith a passage for the boxes, laterally-adjustable supports carrying the said longitudinal bars to admit of them being centrally disposed with reference to the box-passage, yielding connections between said longitudinal bars and adjustable supports, and means for moving the boxes through the aforesaid passage, substantially as set forth.

4. In a machine for gluing the bottoms to boxes, the combination of a fixed bed, a rigid guide at one side of the bed, supports, means for adjusting the supports laterally and longitudinally, longitudinally-disposed bars forming with the bed and guide a box-passage, yielding connections between said longitudinal bars and supports, and means for positively moving the boxes through the box-passage, substantially as specified.

5. In a machine for gluing the bottoms to boxes, the combination of a rigid bed and a fixed guide at one side of the bed, adjustable brackets, longitudinally-arranged bars forming with the bed and guide a box-passage, springs between the longitudinal bars and brackets, connections for varying the tension of said springs and connecting the longitudinal bars with their respective brackets, and means for positively moving the boxes through the box-passage, substantially as delongitudinal bars to cause them to exert a pressure against the box bodies and bottoms for the purpose described, and means for moving the boxes through the box-passage formed by the bed, guide, and longitudinal bars, substantially as described.

7. In a box-machine, the combination of a fixed bed, a rigid guide at one side of the bed,

brackets adjustable longitudinally and laterally with respect to the bed, a longitudinal bar placed opposite the bed and yieldingly connected with the aforesaid brackets, other brackets laterally adjustable with reference to the bed, a longitudinal bar placed opposite the rigid guide and movable toward and from the plane of the bed and connected with the laterally-adjustable brackets, and means for moving the boxes through the passage formed by the bed, guide, and longitudinal bars, substantially as set forth.

8. In a box-machine, the combination of a bed, a guide at one side of the bed, longitudi nal bars disposed opposite to the bed and guide respectively and forming therewith a box-passage, and having their inner ends located a distance from the inner ends of the bed and guide to provide a space for the reception of the box bodies and bottoms, said bars having their inner end portions curved outwardly to ride upon the boxes, yielding and adjustable mountings for the longitudinal bars, and a plunger normally arranged at a distance from the inner ends of the aforesaid longitudinal bars, substantially as and for the purpose set forth.

9. In a box-machine, the combination of the fixed bed for supporting the boxes, a fixed side arranged contiguous to the fixed bed for one side of the boxes, yieldingly-supported bars for the other sides of the boxes, and a plungerfor moving the boxes, substantially as described.
